Title: Single phase induction motor with capacitor start - is fitted with centrifugal switch which is used for cutting out part of capacitance for running
Inventor: WEN HUNG-YING
IPC: H02K17/08
Filed: 1975-02-26
Abstract: The object is to improve both the starting torque and the running torque and power factor. The mains windings (1, 2) are connected in the conventional manner to the supply. The start winding is split (3, 4) with both sections in series and in series also with the running capacitor (5) when at speed. At start a centrifugal switch (7) is closed connecting the start capacitor (6) across one section (4) of the start winding. The start winding acts as a transformer to increase the voltage across the start capacitor and, as the charge varies roughly as the square of the voltage, the effect is to considerably raise the starting torque without increase in capacitance.

Title: Magnetic torque transmission unit for use in vehicles - requires no lubrication or maintenance and assists braking and is fitted with two coupling units
Inventor: RAPPOLT WERNER
IPC: H02K51/00
Filed: 1975-03-21
Abstract: A magnetic torque transmission unit is for use in the power transmission systems of vehicles, and requires no lubrication and or other maintenance and operates in reverse to assist braking. The device consists basically of two coupling units (2, 4) one attached to the drive (1) and to the other to the driven shaft(3). Embedded in the drive shaft unit are a number of permanent magnets (6, 15) mounted so that they match an equal number of similarly shaped electromagnets (7, 13) on the driven shaft unit (4). The windings of these electromagnets are connected in pairs to form circuit loops. When the drive shaft is driven faster than the driven shaft by a certain amount, a current is induced in the electromagnet circuit, which in turn produces a field and the ensuing magnetic coupling between the two shaft units produces an acceleration in the driven shaft.

Title: Overvoltage protection for mains rectifier bridges - using thyristor switched capacitor to absorb excess energy bursts
Inventor: KLOSS ALBERT
IPC: H02H7/12
Filed: 1975-04-07
Abstract: An overvoltage protection circuit for mains rectifier bridge circuits, in which the rectifiers are protected from excess energy burst by means of absorbing these in a capacitance which is then discharged. An overvoltage detection circuit is attached to the mains which is typically but not necessarily three phase, in parallel with rectifier bridge circuits. The protection circuit contains a bridge arrangement of thyristors which switch on when a overvoltage occurs, and charge up a capacitance. At the maximum allowable voltage on this capacitance a further thyristor is switched and an inductive resistive circuit is actuated. The reverse oscillatory signal on this serves to turn off the thyristor and the charged capacitance discharges through an attached load.

Title: Bicycle dynamo geared drive - is coupled to one wheel and has reduced drive losses
Inventor: NOTTER HEINZ JOACHIM DIPL ING
IPC: H02K7/18
Filed: 1976-06-22
Abstract: The drive for the dynamo is taken directly from the axle of either the back or, preferably, the front wheel of the bicycle. Transmission is through gears. The use of this type of drive in place of the conventional friction drive from the type reduces friction looses and thus requires less input energy for a given output. Typically the dynamo is clipped to the front fork. A worm and spur gear transmit rotary motion from the axle into linear one in line with the dynamo axis. A further gear may be incorporated in the dynamo housing. The dynamo may be turned off electrically by a switch, or mechanically by disengaging a clutch.

Title: Electrolytic purification of liquids - in appts. having internal circulation with electrodes in lower quarter of vessel
Inventor: KRAMPITZ JUERGEN
IPC: B03C5/00
Filed: 1976-06-23
Abstract: Aq. liquids are purified from various undesirable materials which can be caused to flocculate by passage through an electric field. This effected a vertical column with an upwards flow, the resulting slurry being taken from the top. The liq. only passes through the electric field in the lower half of the vessel pref. the lower quarter. A separate flow in the opposite direction is maintained at a height less than the total vessel height but higher than the treatment zone. The liq. can be led through a serpentine speed path of large amplitude through a series of treatment zones consisting of upwards flow passages in an electric field. The liquid flows upwards with a velocity significantly below that of the bubbles formed electrolysis and riseing from the electrodes. The process helps to create a system which is very effective for purification but which gives considerably savings in both construction and operating costs c.f. existing plants.
